I registered for the GMAT a few days ago. And yesterday i got a call from an enrollment coordinator at HULT telling me that she viewed my application on the GMAT website and that she thinks my resume is very good. So she said if i apply early i might be eligible for a 20% scholarship at their school.

I applied because i have nothing to lose honestly. But i want to know something.
If i had to choose between Hult International Business School, Cass Business School (City University London), and Warwick Business School, which one would be the best?

All three programs are triple accredited, cost almost the same, and hold very similar rankings as I've seen (Hult is not ranked by the Financial Times though, so should i take this sign as a red flag?)

What are your goals? For traditional MBA roles, City University or Warwick will be a much better choice for most students.

How is the Hult one-year MBA in Boston in terms of career prospects for Indian students?

A one year US MBA at any school is a risky choice for someone who is not a permanent resident. Read the thread linked from my profile page on the best MBAs for international students placement.

A real value of the standard 2-year MBA program at a US business school is the summer internship. This is especially true for international students who are thinking about working in the country after graduation: the internship provides a great way to get your foot in the door of a company who may later be interested in hiring you (plus the added value of having some work experience in the country). Not having this puts many students at a disadvantage when they hit the job market.

What about for US permanent residents? I'm really interested in the one-year format and I've had some good discussions with the Hult recruiting team. Considering this program strongly at this point.

Hult is rarely the best option.
